A standard or scale of measurement. b. A standard dimension, quantity, or capacity. 2. An instrument for measuring or testing.

Over the years I've done a considerable amount of work on pianos using Teflon bushings. And I was taught to use only S&S pins for this very reason. Then I did some testing on my own. I could find no evidence at all that the burr left from the standard flush-cutting side cutters caused any difficulties at all. Yes, there is a slight roughness to the end of the cut, but that is at the outside of the bushing anyway. If it is going to damage anything at all it will be the very outside micrometer or two of the bushing. Certainly not enough to affect the function of the bushing to any discernible extent. Once I figured this out I started using standard centerpins for all of my Teflon bushing work -- thousands of them -- with never a problem. This is a much over-rated problem. Simply get a good set of flush-cutting side cutters -- check with Techni-Tool and Jensen Tools -- and use them properly. (You might also check with them for gram gauges/gages. That's where I got mine. For a lot less than $170. Of course I've had them for 20 or more years...) Del
